Introduction

In this two week laboratory exercise, you will implement a filter to meet a given set of specifications. Unlike previouslabs, you will be graded on the basis of the efficiency of the system that you implement on the DSP. There are two broadways in which you are to optimize your low-pass filter system:

  • We have left the way in which you implement the low-pass filter system completely open and you are free tochoose the method you think will be the most efficient. In filtering techniques , we describe three possibilities:
    • use of an IIR filter
    • overlap-and-add or overlap-and-save using the FFT to perform fast convolution
    • use of multi-rate and multiple filter stages to lower the overall order of the filters required to meetthe specifications.
  • Once you have decided on the overall system for your filter implementation and have verified that it will meetthe given set of filter specifications through simulation, there are many opportunities for optimization in the actualcode that you write for the DSP. You may want to use C in your implementation, but consider the efficiency penaltyincurred from that choice. Use of the various parallel instructions available on the DSP, e.g. ld||mac and st||ld , may yield greater efficiency. Of course, classical optimizations suchas loop-unrolling or the precomputation of data may improve efficiency.

In this lab, you are required to do the following:

  • Choose two techniques described in filtering techniques and answer the prelab questions for those two techniques.
  • Write a complete MATLAB simulation for one filtering technique. You must demonstrate that your simulation meetsthe filter specifications given in the filter specification .
  • Implement the technique that you simulated on the DSP and optimize the system to make it as efficient as possible.You will be graded on the efficiency of your implementation.

A detailed break-down of how you will be graded and the various due-dates can be found in grading .

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
